Identify common letters between the two words to determine their respective numeric codes, then isolate the unique letter.
Mapping the shared letters
Word 1: W H E L P = 2 4 6 8 1. Word 2: H E L P S = 1 2 6 7 4. The letters H, E, L, P are common to both words.
Isolating the unique letters
In W H E L P (24681), the letter 'W' is unique. In H E L P S (12674), the letter 'S' is unique. The digits 2, 4, 6, 1 are present in both codes. The digit '8' is unique to W H E L P, and the digit '7' is unique to H E L P S. Therefore, W corresponds to 8.
A: 1 corresponds to H/E/L/P based on shared codes, B: 2 corresponds to one of the shared letters, C: 4 corresponds to one of the shared letters.
D is correct because by comparing the strings 'WHELP' (24681) and 'HELPS' (12674), we find that 2, 4, 6, 1 are shared digits representing H, E, L, P, leaving 8 as the unique code for W.
When comparing codes, always subtract the set of common letters from the total sets to identify the specific value for the remaining character.
